MACHINE AND PROCESS FOR ENAMELING, COATING, AND CALENDERINQ PAPER ANDPAPER-BOARD.

SPECIFICATION forming part of Letters Patent No. 230,366, dated July 20,1880.

Application filed June 24, 1880. (No model.)

To all whom it may concern:

Be it known that we, CHARLES H. VAN BENTHUYSEN and ARTHUR Borr, of thecity of Albany, county of Albany, State of New principal parts of theapparatus.

' The object of our invention is to combine several machines, so as tocarry out the several processes of coating or applying colors, settingthe colors, drying them in, calendering and brushing the paper, andthen, it required, feeding it to a cutting-machine.

In the drawings, A shows a roll of paper or card-board to be coated onthe grounding-machine B, which isof ordinary construction and need notbe particularly described. After the paper has received the surface ofthe desired color or tint the web is led over the hangingup machine 0,which is of the ordinary construction, to allow the coloring-matter toset. The web is then led over'the drying-cylinders D, which are made upof a suitable number of hollow drums heated by steam, the temperaturebeing easily regulated so as to meet all the requirements ofeachparticular case. The paper or board passes these directly to thecalender-rolls E, in passing through which it receives a smooth flatsurface. It then passes next over the drum F, around the circumferenceof which are a series of brushes, I, adjustable to and from the cylinderF., These brushes are made of bristles, hair, sheep, chamois, or lambskins, felt, fur, or any other suitable material which by friction on acoated surface will produce a finish.

The cylinder F moves at a slow rate of speed, and the brushes orfriction producing appliances at a rapid rate. The paper then passes toa cutting-machine, H, of ordinary construction, where it is cut intoproper lengths. Thus by one operation we arrive at a result whichheretofore has only been reached partially by three or more distinctprocesses and on different machines.

By the use of the large'drum or-cylinder, in

our arrangements with brushes, the number of which can be increased asthe brilliaucy may demand, we receive a product which, as to finish andprinting qualities, has heretofore not been attained.

By the method now in use the enameling Y crushed substancesand metallicparticles, leaving a delicate velvety surface, which readily takes eventhe finest lines.

In the manufacture of the so-called plated papers without any enameling,we pass the paper from the calender-rolls E to the cuttingmachine H.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is

1. The process herein described for coating,

grounding, enameling, and finishing paper and card-board at one and thesame operation by arranging the several separate machines, three ormore, so as to act consecutively and continuously upon the fabric,substantially as set forth and described.

2. The combination of the coating-machine B, the hanging-up machine 0,and the dryingrolls D, as described.

3. The combination of the drying-cylinders D, the calender-rolls E, andthe finishing-machine F, with or without the cutting-machine H,substantially as set forth.
